Outcome of the Use of Continuous Suture in Aortic Valve Replacement by mini-sternotomy
Keywords:
continuous suture, heart valve prosthesis implantation, aortic stenosis.Abstract
Introduction: Aortic stenosis is a complex disease, valve replacement is the only effective treatment and the most frequent valve surgery in the world.
Objectives: To describe the results of the use of continuous suturing in aortic valve replacement by mini-sternotomy.
Methods: A cohort of patients operated on at the Hermanos Ameijeiras Hospital was followed up. The population included 48 patients with aortic valve replacement by ministernotomy between August 2016 and December 2021. Demographic, clinical, intraoperative and postoperative variables were defined.
Results: Dyslipidaemia (83.3%) and hypertension (58.3%) were the most frequent risk factors. The average aortic clamping time was 63.64 minutes and the mean extracorporeal circulation time was 82.20 minutes. The most commonly used prosthesis, according to size, was the St. Jude number 21 (58.3%). There was only one patient with periprosthetic leak.
Conclusions: The use of continuous suture is safe, decreases aortic clamping times and extracorporeal circulation, allows placement of larger prostheses without risk of leakage and avoids the use of Teflon.
